WASHING-MACHINE.

Specification of ALetters Patent.

Patented July 2, 1912.

,Application tiled .Tune 20,l 1910. SerialiNo. 567,794.

To all whom it may concern:

Be it known'thatl, ROBERT E. CAMPBELL, citizen of the United States,residing at \Voodland, in the county of Yolo and State of'Ca'lifornia,have invented certain new and useful Improvements in IVashing-Machines,of which the following is a specification.

My invention relates to an improvement in washing machines of theparticular style or kind upon which I obtained Lette'rs Patent of theUnited States'on the 24th day of September 1907, and numberedm866,912.

In theI accompanying drawings, Figure l is a side elevation of theinvention, and Fig. 2 is an end elevation thereof looking in from ltheleft. tional elevation taken on a line corresponding substantially toFig. 2. Fig. 4 1s a side elevation of the mangle and pinion, and Fig. 5is a cross section thereof on line Fig. el.

The machine upon which this improvement is made is a hand machine anddesigned to be operated exclusively by hand power, but it was Vfounddesirable for various reasons to convert the machine into a powermachineso that it can be run without any expense or outlay of personal labor 1nits operation and be connected up with any suitable source of power,such as a small water motor or electric motor or other power that may beavailable for the purpose.

The invention herein therefore resides essentially in the operatingmechanism as it is connected up with the wash tank and otherparts'substantially as disclosed in my said patent and as will nowappear.

Thus, referring to the said parts, F represents a metallic frame ofsubstantially A shape in side elevation as shown in this instance withthe tank T pivoted olf its middle portion or center of gravity at a tobe off balance substantially as shown and so as to afford a considerabledownward tilting and throw of the long end of the tank as compared withthe short end and thus contribute to the tossing of the wash within thetank for cleansing the same, it being understood that so far as theframe vand the tank together are concerned with spring balancingmechanism there is no novelty claimed in this application.

The tension or balancing mechanism for the'y tank upon theframe consistsginl; the.

Fig. 3 is a longitudinal.` sec` spiral spring S and the two sets of arms2 and 3 respectively with wlnch'said spring is connected and wlnch 1nturn are rigidly 'mounted on the bottom and center of the frame B whichconstitutes the immediat-e support of the tank upon the base frame F.The said link or links 2 are projected in a line ofxaboutforty fivedegrees to the bottom of the tank downward from the short end of thetank .back of its pivot a, While the lilik 3 is shorter and drops fromthe opposite side of said axis a and extends down to connect with thelinks 2 approximately near the point of connect-ion of the spring S. Theeifect and value of this arrangement is thatby means ofthe spring thetank will be held normally in a horizontal position and the spring willoperate to effect this restora-\ tion or position automatically.Therefore the balancing of the tank upon the frame work or base iseifected primarily by the said spring and the said links related asshown and no other mechanism is needed to assist in obtaining thisresult.

The other parts of the machine shown have to do with the operation orwith the power for this purpose, the same, however,

being arranged to cooperate with the said l in the manner shown anddescribed.v

Of course it will be understood that a machine of this kind to getetfective results is necessarily limited in its tilt-ing movement, theidea being that washing of the clothing results from the tossing of the'same With the water to and fro Within the long tank and in which thewash is cleansed by the agitation in the presence of water underthevright conditions of soap and heat'.

Now, having in view this structure as above described, with everythingready 'to be power operated, I provide a segment-al mangle or rack Hsupported from the short end of the tank by arms m pivoted upon .thebottom and short end of the tank and having the rack 7 or teeth thereinadapted to be engaged between the sides of the mangle by a pinion 8 u)on a power actuated shaft 10. A pulley, s eave or sprocket Wheel, orits equivalent, indicated by 12, is mounted upon this shaft and adaptedto receivev power coiinectionsilfrom by beltl or teeth. The said shaftmay be provided witha fly-Wheel if desirable ofr .the wheel 12 itselfmay be 'of'a wveight and construction adapted to serve as a ilyswheel,

s'uch means being necessary With powver, to'

promote 'uniformity of movementpor action in the .tankY an'djto' assistthe springS in doing its work in tilting the tankfas well as overcomingdead' center'sfin the mangle, it being4 understood-that thel said.,'spring is.

The machine being pivoted lentirelyv above the ail'efrenders itimpossible to operate he coperation 'of the mangleA Withfth'e spring is,thatwhen driven by p ovver the swinging mangle or rack from the shortend of the vmachineacts to fix the-exact distance downward of both endsof the tank an makes the action uniorm,-because any suitable sourceequalize the travel bothways. --Wheel also assists inovercolning theinertia of the shifting load in the tank. The spring position: f y Y Thebelt N communicates power to the the revers-'e always comes-,lattinesame places rin the ends ofthe 11i-angle, Y"and the balance Wheel helpsto carry across said ends and Sf also enters into these calculations andisr taken account of in providing a balancey soi thatthe two parts vwillWork in harmony.
